tmux

Table of Contents

1. Launcher

The idea is to need a single key binding, in this case M-t (alt+t), in order to run any tmux commands or shell scripts 

# ~/.config/tmux/tmux.conf

# Launcher
bind-key -n M-t display-popup -E -T " #{host} " -h 60% -w 80% "$HOME/.config/tmux/launcher"

The key binding will run this launcher shell script inside a tmux popup and it will look for a specific line in every scripts under ~/.config/tmux/scripts, the result is a list of scripts to choose from

2. Copy text with copy-mode

Using custom bindings with C-t as prefix 

# ~/.config/tmux/tmux.conf
set -g mode-keys vi
bind-key V copy-mode
bind-key p paste-buffer
bind-key -T copy-mode-vi 'v' send -X begin-selection
bind-key -T copy-mode-vi 'y' send -X copy-selection-and-cancel
  1. Enter copy-mode with prefix V
  2. Begin selection by typing v
  3. Yank (copy) the selected text with y
  4. Then paste anywhere with prefix p

3. Autostart tmux whenever ~/.bashrc is loaded

Using ~/.bashrc to start a tmux session or attach to an existing one

3.1. Single window

# Do not start tmux if inside Emacs and avoid nested tmux sessions
if [[ -z $INSIDE_EMACS && -z $TMUX ]]
then
    if [[ -n $DISPLAY || -n $WAYLAND_DISPLAY || -n $SSH_CONNECTION ]]
    then
        tmux new-session -A -s '0' -n cmd -c "$HOME"
    fi
fi

3.2. Multiple windows

# Do not start tmux if inside Emacs and avoid nested tmux sessions
if [[ -z $INSIDE_EMACS && -z $TMUX ]]
then
    if [[ -n $DISPLAY || -n $WAYLAND_DISPLAY || -n $SSH_CONNECTION ]]
    then
        session_name='0'
        if tmux has-session -t "$session_name"
        then
            tmux attach-session -t "$session_name"
        else
            tmux new-session -d -s "$session_name" -n cmd -c "$HOME"
            tmux new-window -t "$session_name:1" -n rss 'newsboat --quiet'
            tmux new-window -t "$session_name:2" -n music -c "$HOME/music" 'cmus'
            tmux new-window -t "$session_name:3" -n framboise 'ssh framboise'
            tmux attach-session -t "$session_name"
        fi
        unset session_name
    fi
fi

4. Autostart tmux whenever the fish shell is loaded

Add tmux_session at the end of ~/.config/fish/config.fish 

tmux_session

4.1. Single window

# ~/.config/fish/functions/tmux_session.fish
function tmux_session -d "Do not start tmux if inside Emacs and avoid nested tmux sessions"
    if test -z $INSIDE_EMACS and test -z $TMUX
        if test -n $DISPLAY or test -n $WAYLAND_DISPLAY or test -n $SSH_CONNECTION
            command new-session -A -s '0' -n cmd -c $HOME
        end
    end
end

4.2. Multiple windows

# ~/.config/fish/functions/tmux_session.fish
function tmux_session -d "Do not start tmux if inside Emacs and avoid nested tmux sessions"
    if test -z $INSIDE_EMACS and test -z $TMUX
        if test -n $DISPLAY or test -n $WAYLAND_DISPLAY or test -n $SSH_CONNECTION
            set -f session_name '0'
            if command tmux has-session -t $session_name
                command tmux attach-session -t $session_name
            else
                command tmux new-session -d -s $session_name -n cmd -c $HOME
                command tmux new-window -t $session_name:1 -n rss 'newsboat --quiet'
                command tmux new-window -t $session_name:2 -n music -c $HOME/music 'cmus'
                command tmux new-window -t $session_name:3 -n framboise 'ssh framboise'
                command tmux attach-session -t $session_name
            end
        end
    end
end
